The project works by analysing iOS apps and assessing the compatibility with the Windows operating system. From here, Microsoft helps developers optimise the app for Windows, cutting down on the time it takes to bring the app over.

Windows, especially Windows Phone, has a big lack of apps. Many top-of-the-line apps, such as "Clash of Clans" or "Snapchat," are not available on Windows. Microsoft has been trying to plug the gap, and the bridge projects are part of this effort.
